The technical field TO WHICH the INVENTION RELATES

The invention, in General, relates to wireless networks. In particular, the invention relates to a method for indicating a physical change in the external parts of the module of a network node included in a network node in a wireless network, this module of the network node and this node.

The LEVEL of TECHNOLOGY

The size of communication networks from the point of view of the number of nodes that they include, grew rapidly in recent years. One type of communication networks, where this trend is especially strong, is the cellular network.

One reason for this growth is to reduce the size of some of the network nodes such as base stations. Base station currently can be quite small and cover a small area. This provides more flexibility in networks, but also makes them high requirements.

When the number of nodes increases, it is difficult to track that a particular node has been made the change.

One area where the change of a node may be a problem is in the area of identification of the node.

In the network connection there is a need to give each node a unique identifier/address, to enable individual connection with each unit. There are several ways to achieve this automatically.

In some systems there is �also the need to accurately identify, where is the module that generates this node is located, or, in other words, identification information of the block should contain information about the location and not just a unique node address. One example of such a system is a radio access system, consisting of many radio base stations (RBS), where RBS location must be known for radio-frequency (RF) network planning.

Radio access network can be built with many different types of RBS, from Macro to Pico/Femto types. Important for Macro-types is that they are few in number and are located at large distances from each other. Another important aspect Macro RBS is that it contains many plug-in modules, and that it is connected to an external antenna. These types of RBS often require skilled field operators for installation and commissioning.

Important for networks with Pico/Femto RBS is that they can consist of a large number of nodes placed close to each other, and each RBS can contain one removable module that includes an antenna.

In Macro networks "qualified field operators can configure RBS with the necessary information on the location, need to identify.

In Pico/Femto access network the number of field operators is limited as to the number of nodes. In addition, network operators�am may not be allowed to serve some of the nodes, especially Femto nodes, since they can be the private property of the customer. This means that the process of identifying the location information needs to be simplified and reliable. In addition, it may be removed, for example, all RBS, so after you remove at this point there is nothing left that can carry identifying information about the location. This means identifying location information may be lost. Due to the limited number of field operators, maintenance personnel and problems of access can be difficult to provide identifying information about the location of the new or changed node.

There are also other cases where the change of nodes should be registered, for example, if there was any interference in the node.

Thus, there can be several changes to the site, and these changes should be properly treated. Thus, there is a need for the registration of changes made to the network nodes.

Summary of the INVENTION

Thus, the invention is directed to register the physical changes made to the network node.

One object of the invention, therefore, is the detection of physical changes made in the outer part of the module node.

This task, in accordance with �Erwin aspect of the invention, solved by using module network node, comprised in the network node of the wireless communication module and the network node contains:

a displacement detector which detects displacement between the first and second connecting element, and a module of a network node, comprises a first connecting element, and both the connection element is necessary in order to obtain a valid network node, and

a control unit that generates an indication of a physical change of the module of a network node on the basis of the detected displacement.

The task, in accordance with the second aspect of the invention, is solved with the help of a network node in a wireless network, wherein the network node comprises at least one module of the network node. Here the module of a network node in turn contains:

a displacement detector which detects displacement between the first and second connecting element, wherein the module of the network node comprises a first connecting element, and both elements are necessary in order to obtain a valid network node, and

a control unit that generates an indication of a physical change of the module of a network node on the basis of the detected displacement.

The above object, in accordance with a third aspect of the invention, is solved by the method to indicate physical changes in the external part of the module, network node, comprised in the network node in the CE�and wireless communications. Here method contains:

detection of displacement between the first and second connecting element, wherein the module of the network node comprises a first connecting element, and both the connection element is necessary in order to obtain a valid network node, and

the generation of the indication of physical changes in the external part of the module of the network node based on the detected displacement.

The invention has many advantages. It is easier to detect whether a change to the physical appearance of the module in the node or not. This simplifies the handling of the situation and may, for example, to prevent a situation that the module is incorrectly identified as not replaced, as is moved to another location.

Module network node may include a memory module, which is discharged on the basis of the detected displacement.

The method can similarly contain a reset of the configuration module of the network node based on the detection of movement. This reset can be reset to the memory module based on the detection of movement.

The module control unit of the network node may further start the procedure of display processing based on the generated indication. This may include sending an indication of physical changes to the processing device indication via the communication unit.

Therefore, the method can also moderatelysevere procedure of display processing based on the generated indication moreover, the procedure of processing the indication may include sending an indication of physical changes to the processing device display.

A device for treatment of the indication can be the generation device, and the control unit, during execution of the processing procedure of the display can take on new location data from the device for generating location. The processing device display may optionally be another network node in a wireless network, and the control unit can then, during the procedure of display processing, to obtain a new configuration from this other network node via the communication unit. A new configuration with new location data.

The control unit may further receive a network identifier from the another network node during execution of the processing procedure of the display.

The control unit may also perform at least one security measure based on the generated indication. The procedure for processing the display may also contain a procedure for processing licenses for the software.

The control unit can optionally send a signal failure indication on the basis of the detected displacement. The module of the network node may in this case also contain a counter that can change the value on the basis of obnarugen�th move. Signal malfunction indication can then be sent only if the counter value passes the threshold of failure.

The module of the network node may further be a first module of a network node in the set of modules of a network node included in the network node. In this case, the displacement detector can detect the connection or disconnection of the first module of the network node to or from the backplane, which is already connected to at least some of the other modules of the network node in the set. In this case, each of the other modules of the network node will contain identical data on the location, and the control unit will then take location data from at least one of the other connected units.

The displacement detector may also be mechanical and contain the rod, the gear that has many of the provisions of gears, each of which has a corresponding readable pattern, and a means of reading the pattern. The rod can then engage with the pinion and driven by the displacement between the first connecting element and second connecting element. This in turn causes movement of the gear to the new gear position. A means of reading a pattern here reads the pattern and provides it to the control unit. In this situation, the block upravleniyaschitayut current and previous pattern and generates an indication based on the difference.

The first and second connecting elements can additionally be elements of the power connector, and the displacement detector can be electric. In this case, the displacement detector may include a switch that changes the position of the switch and, thus, generates an indication when there is a displacement between the first connecting element and second connecting element. The displacement detector may then also contain the layout of the voltage division that distinguishes the situation of supplying power through displacement between the first and second connecting elements, and other situations power-up.

The first connecting element may be a plug-in element, while the second connecting element may be a corresponding female element. It is also possible that the first connecting element is a female element and the second connecting element is the corresponding plug element.

The module of the network node may also include a positioning block that receives the location of the network node, run the generated indication.

Finally, the module of the network node may be a module of the base station and the network node may be a base station in a wireless LAN network.

It should be emphasized that the term "contains/containing" when used in this description� used to specify the presence of stated properties, systems, steps or components but does not preclude the presence or addition of one or more other properties, systems, steps, components or groups thereof.

DETAILED DESCRIPTION

In the following description for purposes of explanation and not limitation, set forth specific details, such as the particular architecture, interfaces, techniques, etc. to ensure full understanding of the invention. However, for professionals in the field of technology will be obvious that the invention may be implemented in other embodiments that depart from these specific details. In other instances, detailed descriptions are omitted known devices, circuits, and methods so as not to clutter the description with unnecessary detail.

Present the image�the notification relates to a network node in a wireless network.

Here, the wireless network may be a communication network such as the network standard of the project's long-term development (LTE), Universal mobile communication system (UMTS) or Global system for mobile communications (GSM). These are just a few examples of networks that can be implemented in the invention, and it should be understood that the invention may also be implemented in other types of networks such as Wireless local area networks (WLAN). Thus, the communication network may be a cellular network, and the network node may be a base station. One example of one such communication network is schematically shown in Fig. 1.

The illustrative communication network 10 includes a number of base stations, wherein the first base station 14 is a base station forming a node 19 network that uses a physical indication of changes in accordance with the principles of the invention. In addition, the base station is connected to the transport network 12 through which they can communicate with each other and with other network nodes. Here these other network nodes include the first device and the processing device display 16 and 18. The processing device display may, for example, be a network node, such as node operations and maintenance (O&M). For simplicity there are shown only two such node.

Fig. 2 shows a block diagram of a first embodiment of the module 19 of the base station. The module includes inpart network node, formed by the base station. In this example, the module 19 also forms an entire base station 14 in the communication network. Shown here is the module of the base station 19 contains the object 28 to detect physical changes. This object 28 to detect physical changes contains a detector 20 move, the first memory M1 22, the control unit CTU 24 and the communication unit COU 26. Here, the detector 20 displacement is connected with the first memory 22, which in turn is connected to the control block 24. The first memory 22 is here modular memory. Finally, the control block 24 is connected to the connection unit 26.

It should be understood that the module 19 of the network node may include a lot of blocks and functions of other types, such as radiochem, modulator, demodulator, amplifier, antenna, etc. But here they have been omitted to provide a clearer description of the invention. In addition, they are not an integral part of the invention. In addition, these additional blocks associated with the normal functions of the node, i.e. that the present invention is not affected.

The first memory 22 is, preferably, non-volatile memory that can store data when power is absent. The communication unit 26 in this first embodiment, an interface for communication with other nodes in the communication network and may, for this reason, to be an interface, t�Kim as the interface S2 LTE.

Fig. 3 schematically shows a male and female element, here plug ME 30 and female FE element 32 of connector. One of the elements is part of the module, and both elements are necessary to obtain a valid network node. An element that is part of the module, here is the first connecting element, while the element that connect the first connecting element that is the second connecting element. In the example shown here, these elements are provided for supplying the power supply node. In accordance with the first embodiment of the invention they are also used to detect physical changes of the above-mentioned module. Here the plug element 30 includes two contacts, so arranged to enter a corresponding recess or slot of the female element 32. Here the female element 32 is provided with the object 28 to detect physical changes. The object 28 is provided in the cavity, which includes dredging, this cavity is provided for receiving a plug element 30. From this we can understand that in this embodiment of the invention, the female element is part of the module. Thus, it can be seen that in this example, the first connecting element is a female element and the second connecting element is a plug element. Object 28, moreover, is separated from viemo� or sockets, which should dovetail pins. In addition, the object 28 to detect physical changes are placed so that the initial contact between the pin and the recess was set up to detect the connection. Here the connectors are the connectors of the power supply, where the plug connector includes a pair of conductors 34, which provide the power supply for the node. The plug element 30 can be part of a connector for connection to the distribution network. The female element 32 may, on the other hand, to be a part of adapter or Converter to convert the supplied power into a form required for operation of the module. Thus, this means that the plug and socket elements may be elements that are necessary for the operation of the node. Here they are necessary because they provide the energy necessary for the operation of the node.

Thus, in this example of the invention the plug element 30 must be entered in the engaged or inserted in the female element 32 to supply power to the base station and excreted from snagging or disconnect to stop supplying power to the base station. However, enter into engagement or out of engagement of the plug element from the female element in this embodiment of the invention is detected by the object 28 to detect physically� changes which generates a signal I indicating it is a physical change.

Now will be described the first total functioning of the invention with reference to Fig. 1-4, where the latter shows a flow chart of a General method for indicating physical changes in the external part of the first network node.

As noted above, the communication network 10 may include a large number of nodes, and they are at different points in time may be subject to changes, replacements or upgrades. Update here may include replacing all or part of this site. The node can also be changed for other reasons, for example because someone is taking action against the node.

All of these changes are physical and therefore there is a need to detect such physical changes of nodes, which are the physical changes of the external part of the site or part of the site, such as a module of a network node constituting the whole or part of the site. After a change has been detected, it may be necessary to perform one of many appropriate actions. One action can be replaced by a correct node location data. Another may be to those taken ID data communication network, such as network ID, for example, the data transport connection identifier, in�can be in the form of an IP address. These data can, for example, be provided by the second processing device display. An additional effect may be that the module is installed the right software and licenses this software. This may also be the activity of providing security, ensuring that the node is not interfered illegally.

Thus, to launch such actions should occur detect changes in the external parts. This change outer part, in accordance with the invention, is detected through the connection or disconnection of the plug element 30 towards or away from the female element 32. Therefore, if the plug element 30 is inserted or extracted from the female element 32, this movement between the plug element ME 30 and female element FE 32 is detected by detector 20 move the object 28 to detect physical changes, stage 36, which in turn transmits the signals to the detection unit 24 controls. The detector 20 displacement, therefore, is arranged to detect movement between the plug element 30 and a corresponding female element 32. The control block 24 then generates the indication I move or change the outer part of the node, step 38. The control block 24, thus, arranged to generate indica�Oia physical change module of the network node based on the detected displacement. The control block 24, in addition, initiates the procedure of display processing, the stage 39. Thus, this procedure is initiated based on the generated indication. The procedure can be performed by sending the indication I one of the processing devices of the display unit through the communication unit 26, for example, the first processing device 16 display. In this procedure, the display processing unit 24 may be additionally performed with the opportunity to receive a new configuration from another node of a network forming processing device display. This may include receiving location data. The procedure for processing the display may additionally or instead be performed via the control block 24 initiating the procedure internally through the provision of a number of measures, these measures must be met before can be provided or resumed normal functioning. These measures may require that the field operator has performed the action or entered the required data, such as recording location, passwords, code words, etc. the control Unit can thus also be performed with the ability to perform at least one security measure based on the generated indication.

Thus, you can specify that the network node has been made the physical change�approval.

Through the use of the power connector is obtained an additional advantage. Notice of physical change can be sent using the energy from the connector. This means that to receive the notification does not require additional power sources.

There are several implementations of detector displacement, of which three variants, two with the use of electrical components and one based on the mechanical features described here.

The first variant of the displacement detector, which is an electric version based on the alternating current power supply (AC), schematically shown in Fig. 5.

Here, the voltage VAC of the AC power source (AC) is applied between two input terminals, wherein the first input terminal leads to the first end of the first resistor R1 through the first diode D1, while a second input terminal also leads to the first end of the first resistor R1, but through the second diode D2. The first end of the second resistor R2 is coupled to a first end of the first resistor and the second end of the second resistor R2 is connected to the anode of thyristor TH. The cathode of the thyristor TH is connected to ground and the gate connected to the second end of the first resistor R1. The second end of the first resistor R1 is also connected to ground via the switch SW, which can be switch-operated fur�nicheski.

Fig. 5 shows a first voltage V1 at the first end of the first resistor R1, a second voltage V2 at the second end of the first resistor R1 and the third voltage V3 at the connection between the second resistor R2 and the thyristor TH. The second voltage V2 is here also provided to the gate of the thyristor TH.

Now will be described the operation of the detector displacement with reference to Fig. 6, which shows voltages V1, V2 and V3, and an indication of when closes the switch SW.

When the plug element is inserted into the female element, the voltage VAC of the power is taken at the terminals, this voltage VAC is rectified by diodes and fed to the first end of the first resistor R1. This means that the first voltage V1 will act as a constant voltage (DC) that changes from a low to high level, when the male and female elements are engaged. Since the switch SW is not closed, i.e. it is open, the second voltage V2 becomes high through the first resistor R1 and will follow the first voltage V1. This, in turn, leads to the inclusion of the thyristor TH. Thus, the thyristor TH begins to conduct current. The thyristor TH here can be set to turn on if the gate voltage is present above zero. The fact that the thyristor TH conducts current when the first voltage V1 starts to rise, indicated by�OSU thicker the line the level of the third voltage V3, than other voltages. As the thyristor TH conducts current, the third voltage V3 then remains low. Then actuate the switch SW due to the fact that the plug connector element is inserted further into the female element. Therefore, the switch closes or SW_ON is activated. When this occurs, the second voltage V2 becomes low. However, the thyristor TH is still conducts current, and the third voltage V3 will remain low. Thus, you may notice that creates a pulse at the second end of the first resistor R1, which can be used to indicate that it produced a physical change.

Fig. 7 shows the same voltages V1, V2 and V3 in the case that the displacement detector receives power when the plug element is already inserted in the female element. This means that in this case, the switch SW is already closed. Here you can see that when power is supplied, the first voltage V1 is increased from low to high level. It should also be noted that since the switch SW is already closed or turned on, the second voltage V2 remains at a low level. Because the second voltage V2 is low, it also means that the thyristor TH is turned off, which in turn leads to the increase of the third voltage V3 with the first voltage V1. Thus, it comes from the first voltage�the Linux V1.

The combination of these three voltages can be used to indicate that power is supplied. However, they can also distinguish between the case where the power is provided by the insertion of the plug element of the connector in the female connector element, and other cases, such as recovery after a previous power failure. Thus, it was a description of how the can be used the displacement detector in Fig. 5.

Thus, it can be seen that the power connector is designed so that the switch added to the bottom of the cavity of the female element. During the insertion of the plug element of this switch is activated after closing of the power contacts. The time difference between the power supply and activation of the switch is used to create a pulse that can be locked and used as an indication of a physical change. Thus, the object detecting physical changes may take action when the module node in the network is running properly. Thus, this means that when the plug element is partially inserted into the female element is receiving power. After that, when the cable connector is fully inserted into the female element, activates the switch. In addition, the above procedure power can be easily� separated from the procedure of turning on the power supply, when the power plug is already inserted.

Thus, it is possible to distinguish between different scenarios of power such as the power supply with the return of power after an interruption, the power supply circuit when the external switch, the power supply circuit of an internal switch and the power supply when inserting the power connector.

Thus, as can be seen, the plug and socket elements are elements of the power connector, and the displacement detector is electrical and includes a switch arranged to change the position of the switch. This change of position of the switch generates an indication when there is movement between the plug element and socket element. You may also notice that the thyristor TH and the first and second resistors R1 and R2 together form a voltage divider, is arranged to separate the power supply due to the movement between the male and female elements, and other situations power-up.

Fig. 8 shows another electric option, when the supply voltage is a DC voltage. The difference from the variant in Fig. 5 here is that the first terminal leads directly to the first end of the first resistor R1, while the second terminal leads directly to the ground. Thus, removed the two diodes. When the DC voltage VDC when�ladybeetle between the two terminals, this achieves the same type of operation as was described with reference to the first option.

Another possibility is the mechanical variant of the displacement detector. This implementation is schematically shown in Fig. 9. There is a rod 42, which is driven by the movement of the plug element with respect to female element. This rod 42 engages with the teeth of gear 40. Also features a spring-loaded retaining element 44 adjacent to the gear 40, in particular, to hold the teeth of the gear. Each tooth corresponds to a readable pattern 46, for example, in the form of a bar code. There is, finally, the tool 47 reading pattern, is positioned relative to the gear 40 is aligned with the pattern 46 of the prong to read the read of the pattern of the tooth when the gear has some position.

Inserting a plug element into the female element, in accordance with this option, to enter into engagement rod 42 with one prong and thus move the gear 40 and, here, to rotate the gear 40 at one position the gear so that the new gear with the new pattern facing the tool 47 read. The force from the rod 42 will cause, in turn, leave the retaining element 44 from its current position and instead to keep following. Thus, the rod zastavlyaa� gear 40 to rotate in one direction, and the retaining element 44 holds the gear 40 from rotating in the opposite direction to ensure that the gear does not rotate in the opposite direction.

All provisions of gear here may have different codes. As a variant, it is sufficient that the adjacent gear position had different codes, or to three successive positions of the gear had three different code. Thus, the movement of the male and female elements relative to each other causes the tool 47 reader reads different patterns. This difference can then be used to indicate that there was a change in the external part of the node.

Thus, it can be noted that the displacement detector in this embodiment is mechanical and includes a rod 42, the gear 40, having many of the provisions of gears, each of which has a corresponding readable pattern 46 and 47 of the reading of the pattern, where the rod 42 is arranged to enter into engagement with the gear 40, and it is driven by the displacement between the plug element and socket element. Thus, the rod causes the gear to move to a new position, which means 47 reading pattern is made with the ability to read and to provide the control unit. The control unit then examines the current and previous�s patterns and generates an indication based on the difference.

In other words, it is possible, therefore, to see that the position of the rod 42 is changed, what can happen when pressed into the female element when the plug element is inserted into the engagement or disengagement of this female element. This movement causes the gear to make a turn to a new position that will be saved until next time, when the plug and socket elements again engages or will be released from the connection. Each position of the gear will generate a unique pattern. The pattern will be recognized means 47 reading, when an electronic unit is receiving power. When power base station, the pattern read by the recognition device pattern may be compared with a pattern stored in the nonvolatile memory of the last time the unit was turned on. If the patterns are different, the block is replaced or a new system, and software unit actions are taken. Thus, it can be seen that in this case, the patterns of the gears provide a mechanical memory changes.

Gear, thus, can be considered as a mechanical counter, which can be read electronically. This can be useful when the display is used not only power connector that may be necessary to�GDSs; preferably, that the module was moved from its original position/location. When the module is switched on next time, it can detect the event and to take in connection with this action.

Now will be described first preferred method of the object detecting physical changes with reference to figs. 1, 2 and 10, where the latter shows a flow chart of the method of indication of physical changes in the external part of the module node. This option relates to the fact that the node must be provided with location data, such as geo-location data. Another type of location data that can be provided for the node is the position in the network topology.

If the network node is a base station, location information of the base station may not be always based on the way the physical connection of the communication network, because the card network path may not always be correct, or the network may even be absent during the installation of the base station. Therefore, to store location data on another node in the network is not always possible.

Receiving location data automatically using the integrated receiver of Global positioning system (GPS) or similar positioning system is not always possible, because the network node b may�you placed in areas without GPS coverage.

The above discussion shows that in some cases the only option is the placement location data within the network node, and then arises a new difficulty. Location data must be stored in non-volatile memory, to transfer the power failure, and when the module of the network node is replaced by another module of the network node, the location data will accompany the replaced module of the network node. This situation can lead to a host of erroneous location data. The present invention solves this problem.

The method begins with the detection by the detector 20 displacement of the plug element 32 relative to the female element 30, stage 48, which may be performed by using any of the three previously described variants of the detector displacement. This discovery, in turn, causes the discharge of the first memory M1 22, step 50. The first memory 22, thus, is reset upon detection of movement. This means that any location data that are present in this memory 22 are reset. Also, the control block 24 receives information about the detection. The control block 24 may then generate an indication of physical changes in the external part of the base station based on the detected displacement, the stage 52. The control block 24 last� this sends the indication to the I to the first processing device 16 display unit through the communication unit 26, stage 54.

The processing device 16, the display unit may then analyze the indication and to provide in response to the location data. It can, for example, to analyze the network ID or the transport network address of the device that sent the indication, and to find the location data associated with the address that it has previously saved for the network ID, used by the first network node. Here, the location data may be data about a geographic location or location data in the network topology. The control block 24 then receives new location data in response to the indication, step 56, and stores the new location data in the first memory 22, step 58. The control block 24 naturally takes the location data via the communication unit 26. From this you can see that in this example, the processing device the indicating device is generating the location, and in that the processing procedure of the display control unit is arranged to receive new location data from the device generating the location.

Thus, the detection is performed when one module of a network node is replaced by another or joins for the first time. The old location data is then erased, and starts an automatic function system�we in the first processing device indicating that which updates the location data. Additionally or alternatively, if the field operator is present, this field operator can be notified, that must be the new location data.

Thus, it can be seen that in accordance with the invention is to detect when the electronic module, here a base station, mechanically connected with the power source, this event is remembered/recorded so that when the electronic module is started, it determines the situation and can then take action based on the fact that he replaced or is new in the system.

The discovery, described above, was the discovery of the connection of the power connector to the module of a network node in the form of a base station. It should be understood that can be detected, and of another type. Alternatively, it is possible that the detection of the physical change is performed on the basis of the fact that the module is mechanically attached to the mounting device, for example, bolted to the surface. A variant of the latter method is the case when a unit connected to a specific connector cable.

Variant implementation, described above, is, in fact, of the three functions.

Mobile mechanical function, which is influenced by the environment around the module, the function of detecting the moving, perceiving that�agenie movable parts, as exemplified plug and socket elements, has changed compared to its previous position, and a memory function that stores the indication of the modified provisions" for later use. This indication can then be read by the control unit when the module is switched on and in working condition.

Higher memory has been described as a non-volatile memory. Alternatively, an example of which is the mechanical variant of the displacement detector, the memory can be made in the form of a mechanical object, and to operate when the unit is not receiving power. The storage device may also be made in the form of an electronic component when used for indicating the insertion of the power connector or in situations where the electronic module is already receiving power, for example, from an internal battery.

Thus, it is possible to update data on the location of the base station based on the detection of the physical change of an external part such as a connection or disconnection of the power cord.

The first example of use of the invention can consist in that when a new module is installed and powered up, the new situation with the module detected by the object-processing zone. The old location data is then erased from memory. The installer then may be� informed and prompted to enter the new location data to the module. After entering the new location data is then stored in memory in the block.

The second example of use of the invention for the replacement of a faulty module may be that a new module is installed and power is connected. The new situation with the module then is detected by the displacement detector. Old location data erased from the nonvolatile memory in the module. A device for treatment of the indication in the communication network receives information, and current location data is loaded into the node. After that new location data is stored in non-volatile memory in the module.

A third example of use of the invention in combination with respect to the positioning block, such as a GPS unit, it may be that a new module is installed and power is connected. Is found new situation with the module. Old location data erased from the nonvolatile memory. Taken the location from the GPS unit. New location data stored in the nonvolatile memory in the module.

In these examples, the detected physical change made to the network node. However, it should be understood that the network node may consist of several modules. Thus, it is possible that the same type of detection can be achieved in about�the carrying of one or more modules of the node.

Fig. 11 shows a variant of the module 50 of the base station, which can be used as one of several modules in the base station. The module 50 node network can, thus, be the first module of a network node in the set of modules of a network node included in the network node.

This first module 50 includes the same blocks as the module of Fig. 3. In addition, these units operate in the same way. However, in addition it includes a counter 28, and connected to the detector 20 and move the control block 24, block 29 positioning, coupled to the control block 24, and the bus connector 27. The control unit is a control unit module. In addition, the busbar connector 27 is an interface to the connector of the backplane bus.

The positioning block 29 may be a satellite navigation unit that receives the location from the satellite. It may thus be a block of Global positioning system (GPS). Thus, it is possible to obtain location without communication with the network connection.

Fig. 12 schematically shows the backplane 52 network node with multiple slots into which can be inserted modules in the form of printed circuit boards. There is a first slot SL1 54 and the second slot SL2 56, the third slot SL3 58, the fourth slot SL4 60, the fifth slot SL5 62, the sixth slot SL6 64 and the seventh slot S7 66. There is also a second memory 68, the second memory is integrated into the Board memory, and also has the advantage of non-volatile memory. The figure also shows the first module 50 with bus connector 27.

Plug and socket elements there are two connectors, one on Board and one on the map. Here the first slot 54 may be female element, while the bus connector 27 on the circuit Board 50 may be a plug-in element. From this we can understand that in this embodiment of the invention the plug element is part of the first module. In this embodiment of the invention, the first connecting element is, thus, a plug-in element and the second connecting element is a female element. However, to obtain the current network node is required both elements. The movement can be detected in the same manner as described above. However, it detected the card connection to the motherboard and not the connection of the power cord. The connection may, therefore, be a data connection, but also, or in addition to connecting the power source.

Now will be described the operation of the invention in accordance with this last option with reference to Fig. 11, 12 and 13, where the last diagram shows the sequence of some number of steps of the method are performed�x in an embodiment of the method for indicating a physical change in the outer part of the first network node.

As before, the method begins with the detection by the detector 20 displacement of the plug element with respect to female element, step 74, here a moving bus connector 27 relative to the first slot 54.

This runs counter 28, which increases the value CO of the counter, step 76. The CO value of the counter may be a counter value of the card or module. The counter 28 is thus arranged to change the value based on the detected displacement. The control block 24 then retrieves the value CO of the counter and compares it with a threshold counter value, i.e. the threshold of failure. If the counter is above the threshold, step 78, the control block 24 provides a signal indicating failure, step 80. Signal malfunction indication may thus be generated based on the detected displacement. Signal malfunction indication, therefore, preferably is sent only if the counter 28 has a value, passing the threshold of failure. The control block 24 may then send it to another network node, for example, the second processing device 18, the display network connection 10. It is also possible that the fault is indicated in some other way, for example, by using a visual indication on the card itself. The generated indication may be an indication that the card or PE�vy the module inoperable and must be replaced.

However, if the threshold is not exceeded, step 78, the control unit 24 generates the indication I physical changes of the first module based on the detected displacement, step 82, and the first memory 22 is reset, step 84. After that display I is sent by the control block 24. In this variant implementation, it is sent to the other Board modules via bus connector 27, the stage 86. If one of them has location data, this other module will send in response to these location data. Therefore, the control block 24 receives location data from another module via a bus connector 27, the stage 88. This location data is then provided to the first memory 22 and stored therein, step 90. Thus, it can be seen that the first module of the network node is connected to the motherboard 52, which are connected at least some of the other modules of the network node in the set, and each of these other modules of the network node contains identical location data. Then, the control unit is arranged to receive location data from at least one of these other connected modules.

It is possible that if none of the other modules there is no such location data, these data can be obtained using the positioning block 29. In this case, the block 29 is positioned�ing maybe thus, to obtain the position of the network node, run the generated indication.

Another possible option is that the second memory 68 is stored corresponding value of the slot counter and the threshold counter value of the slot assigned to the first slot 54. Both of these values can be obtained by the control block 24 of the second memory 68 via a bus connector 27, as the bus connector 27 of the card 50 is inserted into the slot 54. The control block 24 then compares the value of the slot counter with the threshold value of the counter slot. If the count of the slot crosses the threshold counter value of the slot, the control unit may generate an indication of malfunction of the slot. If the count of the slot does not pass the threshold counter value of the slot, the unit 24 of the control increases or decreases the count value of the slot, and then stores the threshold values of the slot counter and the changed counter value of the slot in the second memory 68. Alternatively, it is possible that instead of the second memory 68 includes a second control unit, the control unit PCB backplane bus, the second control unit comprises a processor, a counter for each slot and the second memory. In this embodiment, the fault indication in relation to the number of vstavlenii cards may be sent to unit 24 of the control module of the control unit Board via a bus soybean�Intel 27 and the first slot 54. The control unit Board can then likewise increase the counter each time slot, when the card is inserted into the corresponding slot, and compare the counter value with the threshold counter slot. A control Board may then specify the fault, if such a threshold has been crossed. As an additional variant, it is possible that the unit 24 of the control module directly reads the count value of the slot via a bus connector 27 and directly provides an indication.

Thus, it is possible to specify how many times a particular card is inserted into the slots, which is the degree of wear of the card. At the same time you can specify how many times the cards were inserted in a specific slot, which is an indicator of wear of the slot and possibly also fees.

The above-described counters, which can be, alternatively, a mechanical and use the previously described principle of the rod can thus be used to predict the lifetime of the module/connector. In many cases there are restrictions on how many times the module can be moved from its place with a performance guarantee that is generally the case for connectors. In the illustrative embodiment of the backplane, as described above, a certain number of cards, thus, is inserted into the backplane, and these cards can mnogokrat� be inserted/removed. The card connectors and the backplane connectors, thus have a guaranteed life span that depends on how many times they were inserted/extracted. This is detected by the functional counter of the type described above on each card.

Each of the above-described connectors backplane may further have an identifier that can be read from cards. The memory access control unit backplane can have all the cards. Non-volatile memory modules may, in turn, be used to store the number of vstavlenii in the backplane. Therefore, when the module is started or it is powered-up, it can check whether it has been inserted into the backplane by reading the value of its counter, and if so, update its non-volatile memory with the new value of the counter. The module can then check whether you have exceeded the maximum number of vstavlenii, and if so, he can send a notification to the operator. After that, the module can update the non-volatile memory on the motherboard with a new counter value and the position of the card. The module can then check whether you have exceeded the maximum number of vstavlenii connector for backplanes (the maximum number of vstavlenii from nonvolatile amateurjapanese cost), and if so, it sends a notification to the operator.

The invention has several advantages. It simplifies the detection, whether there has been a change in the physical appearance of the module in the node. This can prevent the incorrect identification module in communication network, and thereby avoid non-optimal planning of radio frequency (RF) network. The invention also prevents a situation where the field operator goes to the wrong address, replacing the defective unit. As noted earlier, there are many other types of scenarios that can be used in the invention. As noted earlier, this invention can also be used as an indication of interference in the design of the unit. If the module or the cable is retrieved, the operator can actuate the alarm.

This invention can also be used as a triggering mechanism for:

- the process of defining a new identifier of the network connection,

process definitions new identifier ID tags license

or initialization process of a new security.

The invention has been illustrated by the use in the base station. However, it should be understood that the invention is not limited to this and can be used in any communication network containing many nodes.

The module control unit and PCB mo�em to be provided in the form of a processor with associated memory for storing programs, includes computer program code to implement its functionality. It should be borne in mind that this control unit can also be provided in the form of hardware, for example, a specialized integrated circuit (ASIC). Computer program code may also be provided on a computer readable medium, for example, in the form of storage media such as a CD-ROM or memory card that implements the function described above of the control unit of the module being loaded in the above-mentioned memory for storing programs and executable by the processor.

PN shift may be used as group ID. Access terminal may group accepted pilot-signals in one or more pilot-signals group according to their group ID, and select representative pilot-signals from every group of pilot-signals for transmission of message about pilot-signal level. Access terminal may also use grouping of pilot-signals for efficient control of sets.

EFFECT: provision of efficient and reliable communication systems with multiple carriers.

SUBSTANCE: wireless communication network comprises different base stations and subscriber stations. Every base station provides services of broadcasting content transfer to subscriber stations via communication channels of one of the following types: 1) common channel used by multiple subscriber stations, 2) individual channels, every of which is separated for use by separate subscriber station. In response to one or several preset changes of condition, i.e. change of number of subscriber stations that request the program, change of transmission power level used by base station, or in case of other change of network condition, communication channel type used for provisioning of broadcasting content to one or several subscriber stations is switched over.

EFFECT: delivery of broadcasting content with use of errors and individual channels combination, depending on whatever is more preferable in available circumstances.
